Nonparametric Directional Dependence Estimation and Its Application to Cryptocurrency
Axioms, 2023 This paper proposes a nonparametric directional dependence by using the local polynomial regression technique. With data generated from a bivariate copula having a nonmonotone regression structure, we show that our nonparametric directional dependence is

Locally linearly dependent operators [PDF]
Pacific Journal of Mathematics, 2002 Let \(U\) and \(V\) be be vector spaces over a field \(\mathbb F\). Linear operators \(T_1,\ldots,T_n:U\to V\) are said to be locally linearly dependent if \(T_1u,\ldots,T_nu\) are linearly dependent for every \(u\in U\). A classical result by Kaplansky asserts that if \(T\) is a linear operator on a vector space \(X\), then \(T\) is algebraic of ...

The role of path-dependence in the local economic transformation [PDF]
Zbornik Radova: Geografski institut "Jovan Cvijić", 2015 The examination focuses on the issue of path-dependence, which is considered to be the core concept of evolutionary economic geography emphasizing the importance of historical development.

International Journal of Applied Mathematics and Computer Science, 2015 Abstract Many real world data and processes have a network structure and can usefully be represented as graphs. Network analysis focuses on the relations among the nodes exploring the properties of each network. We introduce a method for measuring the strength of the relationship between two nodes of a network and for their ranking ...

t-Wise independence with local dependencies [PDF]
Information Processing Letters, 2008 In this note we prove a large deviation bound on the sum of random variables with the following dependency structure: there is a dependency graph $G$ with a bounded chromatic number, in which each vertex represents a random variable. Variables that are represented by neighboring vertices may be arbitrarily dependent, but collections of variables that ...

Element dependence of local disorder in medium-entropy alloy CrCoNi
AIP Advances, 2021 The medium-entropy alloy CrCoNi is known to have exceptional mechanical properties. To clarify its local structure, we performed extended x-ray absorption fine structure measurement of CrCoNi.
